CVE-2025-26872
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnrestricted Upload of File with Dangerous Type vulnerability in dkszone Eximius allows Using Malicious Files.This issue affects Eximius: from n/a through 2.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceUnrestricted file upload vulnerability in dkszone Eximius allows attackers to upload dangerous file types (e.g., web shells, executables, malicious scripts) without proper validation. Combined with the CVSS 9.9 rating indicating network-exploitable, unauthenticated attacks with complete system impact, attackers can potentially execute arbitrary code on the server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm dkszone Eximius presenceIdentify if the dkszone Eximius application is running in your environment by reviewing installed software, running processes, or web server vhost configurations.Affected if The product is not present in your environment.
-
Locate file upload functionalitySearch for file upload endpoints, forms, or API routes within the Eximius application by reviewing application source code, API documentation, or by probing common upload paths.Affected if No file upload feature exists in your installation.
-
Verify file type validation existsExamine the upload handler code or configuration to determine if MIME type, file extension, or magic byte validation is implemented before file storage.Affected if No file type validation is performed or the validation only checks client-supplied metadata without inspecting actual file content.
-
Check upload directory placementInspect the upload storage path configuration to determine if files are stored within the web document root or in a location accessible via HTTP/HTTPS.Affected if Uploaded files are stored in a web-accessible directory without renaming or extension stripping.
-
Test for unrestricted uploadAttempt to upload a non-image, non-document file type (such as a .php, .exe, or .js file) through the identified upload mechanism to verify if dangerous file types are accepted.Affected if The application accepts and stores executable or script-based file types without blocking.
You are affected if dkszone Eximius is installed with an accessible file upload feature that lacks proper server-side file type validation and stores uploaded files in a web-accessible location.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict allowlist-based file type validation checking both MIME type and file content/magic bytes, store uploads outside web root or rename/strip extensions, and restrict execution permissions on upload directories.
